Common problems we fix in Romney Street
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.
These are often picked up first by site or facilities staff:
- Frame gaps too wide for sealant alone
- Sanitary sealant damaged by following trades
- Frame perimeters left unsealed or poorly sealed
- Existing joints on a refurb that need cutting out and resealing
Extensions at sites like Sevenoaks Hospital (to the south-west of Romney Street) typically sit beside working departments, and the mastic follows strict access rules.
What to look for in a quote
- Whether their applicators hold CSCS cards
- Whether primer will be used where the manufacturer specifies it
- How joint depth will be controlled
- Their plan for phasing and protecting the area
About our construction mastic in Romney Street
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas. Sealing too early only means coming back once others have damaged it. If you are dealing with window and door perimeters that won’t pass inspection and internal caulk splitting as the building dries out, we can help. Whoever orders the work in Romney Street, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Romney Street, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Aftercare for building managers
A few simple habits keep the new joints working:
- Flag uneven or tapered frame gaps early
- Record the products used in the O&M file
- Plan external elevations with the weather in mind
- Release areas for mastic once other trades have finished in them
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out and keeps handover on track.

What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Halls, stores and units around places like Romney Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Pricing mastic packages depends on quantities, condition and access. Ask us for a fixed quote.

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we have sealed
- Specifying the product where the designer hasn’t
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think before you book.
Surfaces we seal
- Window and door perimeters
- Brick and block movement joints

Contractors’ notes for Romney Street
Rainfall across the South East, Romney Street included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Romney Street is about 18 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
Older buildings in the area around Romney Street, such as Lullingstone Castle (2.3 miles north-west of Romney Street), need care when sealed: the product has to suit soft or historic materials. Units on estates such as West Kingsdown Industrial Estate (to the north-east of Romney Street) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Your questions answered
Is hospital work, at somewhere like Sevenoaks Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Romney Street, such as West Kingsdown Industrial Estate?
Yes. Our area takes in Romney Street and its surroundings, with estates and business parks such as West Kingsdown Industrial Estate included. A few photos and the unit address let us price the work.
Do you work in Romney Street?
Yes. We cover Romney Street, and you can ring 01277 525 020 or send details through our quote form to get started.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can staff carry on working while you are here?
Typically, yes. Phased work can be planned so areas stay in use.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
